Which are the key points of the tool Maraiser?

In a Managed Aquifer Recharge system (MAR) with Alternative Water Resources (AWR), it is crucial to transform the risk factors into quantifiable indicators. By doing so, it is possible to systematically monitor and assess risks in real time, enabling timely interventions and adjustments to mitigate them effectively.

Within this framework, MARCLAIMED partners from Aigües de Barcelona, Agència Catalana de l’Aigua and CETAQUA designed Maraiser to help manage MAR systems by establishing a full set of health, environmental, and performance risk indicators, based both on legislation requirements and operational constraints.

• Health risks focus on potential threats to human wellbeing, including the presence of pathogens, chemical contaminants, and emerging pollutants that could affect water users.
• Environmental risks include potential contamination of groundwater ecosystems, accumulation of persistent micropollutants, and alteration of natural hydrological cycles and habitats.
• Operational risks involve system performance issues, maintenance challenges, and unintended consequences of recharge activities, such as clogging or geochemical reactions.

Risk indicators under different approaches

Therefore, the critical points of each MAR system on the project are identified, and both alert and critical thresholds are defined. Based on them, whenever a data set is out of the desired range, automatic alarms are raised , and the required actions are taken correspondingly, in order to restore the system operation and set it back to its most optimal performance.

In a nutshell: Maraiser empowers decision-makers and operators to manage risks more effectively, ensuring human health, ecological integrity, and optimal yield in water recharge systems.
